Thomas,
All fuel lines are 3/8". I initially planned for 1/2"
through the Andair using the 20-25 duplex valve. Got talked out of it. The RV10
kits for the 260hp Lyc are using 3/8 lines. The 20-25 value supports 1/2 NPT /
AN8 connections for the suction side. 3/8 for the return. The 20-20 valve is 3/8
both directions with AN6.
Each pump has
it's on filter not each tank. Some of the short sections of fuel line between
the filters and pumps may change to fittings depending on room and area required
for servicing the filters and pumps. I am also not ruling out some flex hoses on
the low pressure side. Need to get my Andair. I ordered it three months ago.
Every week they tell me it is ready to ship :( still not
joy!
Fuel Rail parts and injectors?????? Still waiting to see if
Bruce and Tracy's are going to offer a Renesis intake.. :)

Bobby,
IIUIR, you are pluming:
1) Each tank to the Andair
2) From the Andair to the pumps
3)...rest of the plan
If so, Why not use 1/2" lines Until the
pumps?
Do you use any kind of by-pass for the
filters?

Expensive
This is hopefully
my final design for my fuel system.
1. Use Andair
duplex valve and mount to floor with extension. The 10 has a console.
2. Use (expensive)
Y blocks to reduce bends and provide sensor ports.
3. Filter before
and after pumps.
4. Auto fail over
circuit to switch on second pump at 28 psi.
5. High pressure
bleeder.
6. 3/8 lines.
7. All cabin fuel
plumbing mounted to plate on floor.
8. Firewall
bulkheads on cool side of engine.
The pressure drop
and flow rate of the AC Delco Filters is unknown...AC Delco will not provide
specifications. Will need to measure.
This is the same
basic configuration the EGG's are running so it should provide a larger group
of planes with this design in the air sooner.
Flame
away!!
